Abstract:
OBJECTIVE:To prepare hydroxycamptothecin sustained-release tablets and to optimize its preparation technology and formulation.METHODS:The preparation technology and formulation were optimized by orthogonal experiment taking the type of excipient polylactic acid (A),tabletting pressure (B),ratio of HCPT to PLA (C) as factors with the deviation degree of the accumulative release percentage as evaluation index.Then the optimized results were verified.RESULTS:The optimal technology and formulation were as follows:A was PLA (20 000),B was 250 N,C was 1∶5.The deviation degree of the formulation was verified to be 2.963.CONCLUSION:The hydroxycamptothecin sustained-release tablets prepared in optimized preparation technology and formulation are up to the standard on preparation.
